Hadith.919 - Al-Fadl ibn Shadhan reported from Imam al-Rida (as): "Another reason (for the seven takbirs) is that the original structure of the prayer is two Rak'ah (units), and the opening of these two Rak'ah with seven takbirs corresponds to the takbir for the opening, the takbir for bowing (Rukuh), and the two takbirs for the two prostrations (sujood) in the first rak’a, followed by the takbir for bowing in the second rak’a and the two takbirs for the two prostrations in the second rak’a. Thus, if a person begins their prayer with seven takbirs and later forgets or misses one of the opening takbirs, it does not cause a deficiency in their prayer."
